Ring Swap (FewV2) pool discovery references for Ethereum, BNB Smart Chain, HyperEVM, and MegaETH.

Ring Swap Pools by Network

This page lists pool discovery references by network. It does not repeat the full deployment tables; Factory addresses appear only where they help integrators discover pools. Routers, wrappers, Permit2, and the complete contract directory are maintained in Contract Deployments. Both pages cover Ethereum (1), BNB Smart Chain (56), HyperEVM (999), and MegaETH (4326) in the same order.

Pair addresses are chain-specific. Select the network first, then use that network's Ring Swap Factory and FewToken mappings.

For automated ingestion, use the Ring Swap deployment manifest. The manifest records the same contract, FewToken, and Pair relationships without requiring table scraping.

Some partner APIs call Ring Swap liquidity FewV2. This is the network-specific pool reference for that integration name.

This page publishes stable integration references, not live liquidity metrics. Reserves and TVL change every block and are intentionally omitted.

Ring Swap factories are permissionless. Anyone can create a pair when the contracts allow it. A pair in a factory, this table, a token list, or an explorer is not proof that Ring reviewed or endorses the assets. Use an application-level allowlist and verify every FewToken through FewFactory and every pair through the Ring Swap Factory.

Do not transfer assets to a pair address

Pair addresses hold pool reserves and LP accounting. They are not user deposit addresses. Use a reviewed Router or contract integration with a minimum output or maximum input, future deadline, verified recipient, and fresh simulation.

Ethereum Mainnet​

Discover Ethereum pools through the live explorer or enumerate the Ring Swap Factory onchain. Verify each pair and its FewToken mappings before including it in a route.

The table above is curated. It is not a complete factory index, a recommendation, or a guarantee of current liquidity. Integrators that enumerate the permissionless factory must still apply their own token and pair allowlist and validate both FewToken addresses through FewFactory.

The published @ring-protocol/[email protected] does not support MegaETH FewToken and pair derivation. Do not use its MegaETH address helpers until the SDK support table names a fixed published version.

Pool state​

These tables provide deployment references, not live liquidity data. Verify factory and FewToken mappings onchain, read current reserves, and simulate the intended trade before execution.

Historical factory counts, mapping checks, and reserve checks are in the status snapshot, with a verification block for each network. Those results apply only to the recorded blocks and do not establish current liquidity, asset quality, approval safety, or suitability for a particular order size.
